Description

BLOC PROJECTEUR POUR VEHICULE AUTOMOBILE PROJECTOR BLOCK FOR MOTOR VEHICLE
L'invention concerne un bloc projecteur pourvu d'un soutien de bouclier pour véhicule automobile ainsi qu'un ensemble de soutiens d'un tel bouclier. De manière classique, les boucliers en polypropylène nécessitent des supports spécifiques pour répondre aux critères de qualité perçue, tels que les jeux entre le bouclier et les autres parties de la carrosserie du véhicule, et aux sollicitations des charges statiques et dynamiques. Généralement, afin de maîtriser les jeux entre le projecteur et le bouclier, on réalise une liaison directe entre le projecteur et le bouclier. A cet effet, le bouclier est par exemple fixé sur un support situé sous le projecteur et solidaire de ce dernier. On désigne par bloc projecteur l'ensemble formé du projecteur et du support de bouclier. Toutefois, les contraintes dues au poids du bouclier ainsi que les charges statiques et dynamiques importantes exercées sur le bouclier, sont alors transmises au support sous projecteur lequel n'est pas conçu pour supporter de telles contraintes. Il en résulte une fragilisation du bloc projecteur, notamment au niveau de la fixation entre le projecteur et le support, ou une détérioration du projecteur. L'invention vise à pallier ces inconvénients en proposant un bloc projecteur pour véhicule automobile, comportant un projecteur dont la paroi inférieure est solidaire d'un support de bouclier du véhicule, le bloc projecteur comportant sur sa partie arrière d'extrémité au moins une première fixation à la structure du véhicule, caractérisé en ce que la partie avant du support située en regard de la paroi inférieure du projecteur est apte à supporter le bouclier du véhicule de manière à le maintenir à une distance prédéterminée sous cette paroi inférieure, et en ce que, à distance de la première fixation, sur leur partie avant, la paroi inférieure du projecteur et le support comportent au moins une fixation directe commune sur la structure du véhicule. Une telle fixation directe commune permet de transmettre une partie des efforts exercés sur le bouclier ou le bloc projecteur directement à la structure du véhicule. Avantageusement, le support comprend sur sa partie avant à distance de cette fixation commune et de la première fixation, au moins un pied d'appui apte à reposer sur un élément de la structure du véhicule. Ce pied d'appui est situé à un endroit où le support ou le projecteur, ne sont pas directement reliés à structure du véhicule, de sorte que lors d'un fléchissement notable du support, sous l'effet d'une charge importante, le pied d'appui va venir s'appuyer sur la structure du véhicule et lui transmettre les efforts. La conception d'un ou plusieurs pieds d'appui permet de réduire l'épaisseur du support sans nuire à la robustesse du bloc projecteur. Avantageusement, le projecteur et le support sont reliés par des pattes de fixation verticales. Une liaison robuste est ainsi obtenue entre les deux pièces. De préférence, les pattes de fixation verticales du support sont situées à proximité de la partie avant du support destinée à supporter le bouclier, de manière à limiter tout effet de levier entre ces pattes et la partie supportant le bouclier, et à améliorer la robustesse de l'ensemble. Avantageusement, le support présente des orifices de fixation d'axe vertical aptes à assurer son positionnement par rapport au projecteur. De préférence, la partie avant du support, destinée à supporter le bouclier, est formée d'une pluralité de surfaces de support s'étendant sensiblement horizontalement le long du bord inférieur du projecteur. Le bouclier peut ainsi être soutenu régulièrement le long du projecteur. Avantageusement, le support est réalisé dans une matière à haute limite d'élasticité de manière à subir des contraintes relativement élevées sans se déformer ou se rompre. L'invention concerne également un ensemble de soutiens pour bouclier de véhicule automobile comportant deux blocs projecteurs selon l'invention disposés de part et d'autre du véhicule de telle sorte que les supports soient situés sensiblement au dessus d'une partie de la structure du véhicule, et au moins une patte de soutien disposée entre les deux blocs projecteurs apte à être fixée sur la structure du véhicule. Le bouclier dispose ainsi de soutiens répartis sur sa longueur. Avantageusement, trois pattes de soutien sont prévues entre les blocs projecteur afin de réduire la longueur des parties de bouclier sans points de soutien. Avantageusement, les blocs projecteurs et les pattes de soutien sont fixés sur la traverse chocs du véhicule. L'invention est maintenant décrite en référence aux dessins annexés, non limitatifs, dans lesquels : la figure 1 est une représentation en perspective de la structure avant d'un véhicule automobile comportant un ensemble de soutiens de bouclier selon l'invention ; la figure 2 représente une vue en perspective de dessus d'un bloc projecteur selon l'invention ; les figures 3 et 4 représentent des vues en perspective de côté et arrière du bloc projecteur de la figure 2 ; - la figure 5 est une vue en coupe longitudinale représentant le bord d'un bouclier soutenu sous le projecteur par le support de projecteur ; la figure 6 est une vue en coupe longitudinale du bouclier supporté par une patte de soutien disposée entre les blocs projecteurs. Dans la description, les termes avant et arrière se réfèrent à l'avant et l'arrière du véhicule suivant la direction longitudinale X de ce dernier, dirigée vers l'arrière du véhicule. Les pièces sont décrites dans une position identique à leur position de montage sur le véhicule. La figure 1 représente la structure avant d'un véhicule comportant deux blocs projecteurs avant 1 montés sur les bords latéraux du véhicule au dessus de la traverse chocs 2. La traverse chocs 2 supporte des pattes de soutien 3 pour le bouclier du véhicule situées entre les deux blocs projecteurs. Chaque bloc projecteur est formé d'un projecteur comprenant un boîtier 4 fermé par une glace externe 5, et d'un support de bouclier 6. Le boîtier 4 et le support 6 sont décrits en référence aux figures 2 à 4. Pour plus de clarté la glace a été omise sur ces figures. Le boîtier 4 présente une paroi inférieure 7 qui s'étend sensiblement horizontalement et située en regard du support 6. Le bord libre de cette paroi, appelé bord inférieur 8 se prolonge sur tout le pourtour du boîtier pour la fixation de la glace. La partie supérieure du bord du boîtier est désignée par la référence 9. Le boîtier présente, vu de dessus, une forme générale coudée dont une partie s'étend vers l'arrière du véhicule sensiblement dans la direction longitudinale X et l'autre partie s'étend vers l'avant dans une direction proche de la direction transversale Y du véhicule. Sur son bord supérieur 9, le boîtier présente deux pattes de fixation 10 qui s'étendent dans un plan sensiblement horizontal. Ces pattes 10 sont situées respectivement sensiblement au milieu du bord supérieur 9 et du côté de l'extrémité avant du bord supérieur 9 du boîtier. La figure 1 montre que ces pattes 10 sont fixées sur une partie transversale de la structure du véhicule par des fixations (vis ou analogues) d'axe sensiblement vertical. Au niveau de son extrémité arrière, le boîtier 4 comporte une autre patte de fixation 11 destinée également à être fixée sur la structure du véhicule. Cette patte fait saillie de la paroi inférieure 7 sensiblement verticalement vers le bas. Sur sa paroi inférieure 7, le boîtier présente une patte de fixation 12 qui s'étend sensiblement horizontalement vers l'avant du véhicule en saillant du bord inférieur 8. Cette patte 12 est située sensiblement au milieu du bord inférieur, à distance de la patte de fixation 11 arrière. Le boîtier 4 présente en outre sur sa paroi inférieure 7, à distance du bord inférieur 8, une pluralité de pattes 13 qui s'étendent verticalement et destinées à être solidarisées au support 6. Ces pattes s'étendent de préférence parallèlement les unes aux autres afin de faciliter la fixation du support 6 sur le boîtier. Le support 6 se présente sous la forme d'une plaque moulée, de préférence dans une matière à haute limite d'élasticité, qui s'étend sensiblement horizontalement, et qui est destinée à venir contre la paroi inférieure 7 du projecteur, sous cette dernière. Elle présente une forme générale coudée vue de dessus, similaire à la forme du boîtier, dont une extrémité 14 est dirigée vers l'arrière du véhicule sensiblement dans la direction longitudinale X et l'autre extrémité 15 s'étend sensiblement suivant la direction transversale Y, en avant . On désigne par 16 et 17, les faces supérieure et inférieure respectivement du support, et par 18 et 19, les bords avant et arrière respectivement du support. Le support comporte sur son extrémité arrière 14 une patte de fixation 20 verticale, s'étendant sensiblement suivant la direction longitudinale X, destinée à être fixée sur la structure du véhicule. Sur sa face supérieure 16, saillant de celle-ci, le support présente une pluralité de pattes verticales 21 parallèles les unes aux autres et destinées à coopérer avec les pattes verticales 13 du boîtier. A cet effet, elles sont réparties le long du bord arrière 19 du support. A proximité de son bord arrière 19, le support présente plusieurs orifices 22 de positionnement d'axe vertical, destinés à coopérer avec des pattes correspondantes solidaires de, ou avec des orifices correspondants (non représentés) prévus dans la paroi inférieure 7 du boîtier. Les parties du support présentant ces orifices sont de préférence conformées de manière à venir en appui contre la paroi inférieure 7 du boîtier, ou contre des pattes solidaires de ce dernier. Le support peut ainsi être aisément positionné de manière correcte par rapport au boîtier et peut être conçu pour faire partie intégrante de l'isostatisme du bloc projecteur. Le support 6 présente en outre un orifice d'axe vertical 23 disposé de manière à pouvoir coopérer avec la patte de fixation 12 du boîtier. Cette patte 12 et cet orifice 23 permettent une fixation commune directe du boîtier et du support sur la structure du véhicule. Sur sa face inférieure 17, le support est pourvu de deux pieds d'appui 24 d'axe vertical, destinés à venir prendre appui sur la traverse chocs 2 de la structure du véhicule. Ces pieds d'appui 24 sont situés à proximité du bord avant 18, du côté de son extrémité avant 15, distante de la patte de fixation 20. Enfin, sur sa face supérieure 16, le long de son bord avant 18, le support est pourvu d'une pluralité de surfaces de support de bouclier 25 qui s'étendent sensiblement horizontalement. Les orifices 22 sont de préférence situés le plus près possible de ces surfaces afin de limiter l'effet levier entre les surfaces 25 et les fixations traversant ces orifices 22. Le support 6 est fixé sur la paroi inférieure 7 du boîtier de sorte que son bord avant 18 soit disposé légèrement en avant du bord inférieur 8 du boîtier, sous une partie horizontale de la glace 5 (figure 5). Ces surfaces 25 sont moulées de manière à être situées à une distance sensiblement constante de la glace lorsqu'elle est fixée au projecteur. Elles sont de préférence réparties de manière discontinue de sorte que l'épaisseur du support entre les surfaces de soutien peut être réduite. Cette épaisseur moindre entre les surfaces permet notamment le passage de clips qui servent à fixer une garniture sur le bord supérieur du bouclier. L'ensemble des points de fixation entre le support et le boîtier sont de préférence répartis le long du support pour équilibrer les transferts de charge. En outre les pieds d'appui 24 pourraient être remplacés, lorsque l'encombrement le permet, par une fixation directe commune du boîtier et du support sur la structure du véhicule pour assurer le transfert de charge du boîtier, ou du support, vers la structure. La figure 5 représente le bord supérieur 26 du bouclier qui repose sur une surface 25 du support de projecteur sous la glace 5. Une garniture de bouclier 27, fixée sur le bord supérieur 26 par des clips, comble en partie l'espace entre le bouclier et la glace. Le bouclier est ainsi soutenu sous le projecteur sensiblement sur toute la longueur de ce dernier de sorte que le jeu entre le projecteur et le bouclier est maîtrisé. Tel que représenté figure 5, les surfaces 25 sont de préférence situées à une distance d de la glace 5 suivant la direction longitudinale X, de manière à minimiser les efforts transmis à la glace lors d'un choc frontal. Le bouclier est également soutenu entre les deux blocs projecteurs par un ensemble de trois pattes de soutien 3 fixées sur la traverse chocs 2. La partie verticale de chaque patte est fixée sur la traverse, tandis que leur extrémité 3a supérieure s'étend dans un plan sensiblement horizontal et sert de support au bouclier. Ces pattes sont réparties entre les blocs projecteurs de manière à offrir des points de soutien régulièrement espacés au bouclier. De préférence, ces trois pattes font partie d'une même pièce. La figure 6 représente le bouclier 28 dont une partie de la face interne est en appui sur l'une des pattes de soutien 3. Ces pattes 3 sont de préférence en métal. L'ensemble formé des blocs projecteurs et des pattes de soutien assure ainsi des points de support pour le bouclier qui sont répartis de préférence régulièrement sensiblement tout le long du bouclier, les extrémités du bouclier étant fixées directement sur la structure du véhicule. The invention relates to a projector unit provided with a shield support for a motor vehicle and a set of supports for such a shield. Conventionally, polypropylene shields require specific supports to meet the criteria of perceived quality, such as the games between the shield and the other parts of the vehicle body, and the stresses of static and dynamic loads. Generally, in order to control the games between the projector and the shield, a direct connection is made between the projector and the shield. For this purpose, the shield is for example fixed on a support located under the projector and secured to the latter. Projector block is the set formed by the projector and the shield support. However, the stresses due to the weight of the shield as well as the significant static and dynamic loads exerted on the shield, are then transmitted to the under-projector support which is not designed to support such constraints. This results in a weakening of the projector block, especially at the fixing between the projector and the support, or a deterioration of the projector. The invention aims to overcome these disadvantages by proposing a motor vehicle headlamp unit, comprising a headlamp whose lower wall is integral with a vehicle bumper support, the headlamp unit having on its rear end portion at least a first fastening to the vehicle structure, characterized in that the front part of the support located opposite the lower wall of the headlamp is able to support the shield of the vehicle so as to maintain it at a predetermined distance under this lower wall, and in that that, at a distance from the first attachment, on their front part, the lower wall of the projector and the support comprise at least one common direct attachment to the vehicle structure. Such a common direct attachment makes it possible to transmit a part of the forces exerted on the shield or the headlamp unit directly to the structure of the vehicle. Advantageously, the support comprises on its front part at a distance from this common attachment and from the first attachment, at least a support foot adapted to rest on an element of the vehicle structure. This support foot is located at a place where the support or the projector, are not directly connected to the structure of the vehicle, so that during a significant deflection of the support, under the effect of a significant load, the foot support will come to rely on the structure of the vehicle and transmit the efforts. The design of one or more support feet reduces the thickness of the support without harming the robustness of the projector block. Advantageously, the projector and the support are connected by vertical fixing tabs. A robust connection is thus obtained between the two parts. Preferably, the vertical fastening tabs of the support are located near the front portion of the support intended to support the shield, so as to limit any leverage between these tabs and the portion supporting the shield, and to improve the robustness of the all. Advantageously, the support has vertical axis fixing holes capable of ensuring its positioning relative to the projector. Preferably, the front portion of the support for supporting the shield is formed of a plurality of support surfaces extending substantially horizontally along the lower edge of the projector. The shield can be supported regularly along the projector. Advantageously, the support is made of a material of high yield strength so as to undergo relatively high stresses without deforming or breaking. The invention also relates to a set of supports for motor vehicle shield comprising two projectors blocks according to the invention disposed on either side of the vehicle so that the supports are located substantially above a part of the structure of the vehicle. vehicle, and at least one support leg disposed between the two projectors blocks adapted to be fixed on the vehicle structure. The shield thus has supports distributed along its length. Advantageously, three support legs are provided between the projector blocks in order to reduce the length of the shield parts without support points. Advantageously, the headlamps and the support legs are fixed to the crossmember of the vehicle. The invention is now described with reference to the accompanying non-limiting drawings, in which: FIG. 1 is a perspective representation of the front structure of a motor vehicle comprising a set of shield supports according to the invention; FIG. 2 represents a perspective view from above of a headlamp unit according to the invention; Figures 3 and 4 show perspective side and rear views of the projector block of Figure 2; - Figure 5 is a longitudinal sectional view showing the edge of a shield supported under the projector by the projector bracket; Figure 6 is a longitudinal sectional view of the shield supported by a support lug disposed between the projectors blocks. In the description, the terms front and rear refer to the front and rear of the vehicle in the longitudinal direction X of the latter, directed towards the rear of the vehicle. The parts are described in a position identical to their mounting position on the vehicle. FIG. 1 shows the front structure of a vehicle comprising two front projector blocks 1 mounted on the lateral edges of the vehicle above the transom 2. The transom 2 supports support tabs 3 for the vehicle shield located between the two projectors blocks. Each projector block is formed of a projector comprising a housing 4 closed by an outer mirror 5, and a shield support 6. The housing 4 and the support 6 are described with reference to Figures 2 to 4. For clarity ice has been omitted from these figures. The housing 4 has a bottom wall 7 which extends substantially horizontally and located opposite the support 6. The free edge of this wall, called the lower edge 8 extends over the entire periphery of the housing for fixing the ice. The upper part of the edge of the housing is designated by the reference 9. The housing has, seen from above, a generally bent shape, a portion of which extends towards the rear of the vehicle substantially in the longitudinal direction X and the other portion extends forward in a direction close to the transverse direction Y of the vehicle. On its upper edge 9, the housing has two fixing lugs 10 which extend in a substantially horizontal plane. These tabs 10 are respectively substantially in the middle of the upper edge 9 and the side of the front end of the upper edge 9 of the housing. Figure 1 shows that these lugs 10 are fixed on a transverse part of the vehicle structure by fasteners (screws or the like) of substantially vertical axis. At its rear end, the housing 4 comprises another fixing lug 11 also intended to be fixed on the vehicle structure. This tab projects from the lower wall 7 substantially vertically downwards. On its lower wall 7, the housing has a fastening lug 12 which extends substantially horizontally towards the front of the vehicle protruding from the lower edge 8. This lug 12 is located substantially in the middle of the lower edge, at a distance from the leg fixing 11 rear. The housing 4 further has on its lower wall 7, at a distance from the lower edge 8, a plurality of tabs 13 which extend vertically and intended to be secured to the support 6. These tabs preferably extend parallel to one another to facilitate the attachment of the support 6 on the housing. The support 6 is in the form of a molded plate, preferably in a high yielding material, which extends substantially horizontally, and which is intended to come against the lower wall 7 of the projector, under the latter . It has a generally bent shape seen from above, similar to the shape of the housing, one end 14 is directed towards the rear of the vehicle substantially in the longitudinal direction X and the other end 15 extends substantially in the transverse direction Y , forward. 16 and 17 denote the upper and lower faces respectively of the support, and 18 and 19, the front and rear edges respectively of the support. The support has on its rear end 14 a vertical bracket 20, extending substantially in the longitudinal direction X, intended to be fixed on the vehicle structure. On its upper face 16, protruding from it, the support has a plurality of vertical tabs 21 parallel to each other and intended to cooperate with the vertical legs 13 of the housing. For this purpose, they are distributed along the rear edge 19 of the support. Near its rear edge 19, the support has a plurality of vertical axis positioning orifices 22 intended to cooperate with corresponding tabs integral with or with corresponding orifices (not shown) provided in the lower wall 7 of the housing. The portions of the support having these orifices are preferably shaped so as to bear against the lower wall 7 of the housing, or against lugs integral with the latter. The support can thus be easily positioned correctly relative to the housing and can be designed to be an integral part of the isostatism of the projector block. The support 6 further has a vertical axis orifice 23 arranged so as to cooperate with the fastening lug 12 of the housing. This lug 12 and this orifice 23 allow a direct common attachment of the housing and the support on the vehicle structure. On its lower face 17, the support is provided with two support legs 24 of vertical axis, intended to bear on the crossbar shocks 2 of the vehicle structure. These support feet 24 are located near the front edge 18, the side of its front end 15, remote from the bracket 20. Finally, on its upper face 16, along its front edge 18, the support is provided with a plurality of shield support surfaces 25 which extend substantially horizontally. The orifices 22 are preferably located as close as possible to these surfaces in order to limit the lever effect between the surfaces 25 and the fasteners passing through these orifices 22. The support 6 is fixed on the bottom wall 7 of the housing so that its edge before 18 is arranged slightly in front of the lower edge 8 of the housing, under a horizontal portion of the window 5 (Figure 5). These surfaces are molded so as to be located at a substantially constant distance from the ice when attached to the projector. They are preferably distributed in a discontinuous manner so that the thickness of the support between the support surfaces can be reduced. This lesser thickness between the surfaces allows in particular the passage of clips which serve to fix a lining on the upper edge of the shield. The set of attachment points between the support and the housing are preferably distributed along the support to balance the load transfers. In addition, the support feet 24 could be replaced, when space permits, by a common direct attachment of the housing and the support on the vehicle structure to ensure the charge transfer of the housing, or support to the structure. FIG. 5 represents the upper edge 26 of the shield which rests on a surface 25 of the projector support under the window 5. A shield trim 27, fixed on the upper edge 26 by clips, fills in part the space between the shield and ice cream. The shield is supported under the projector substantially along the entire length of the latter so that the play between the projector and the shield is controlled. As shown in FIG. 5, the surfaces 25 are preferably situated at a distance d from the ice 5 in the longitudinal direction X, so as to minimize the forces transmitted to the ice during a frontal impact. The shield is also supported between the two projector blocks by a set of three support lugs 3 fixed on the crossbar shocks 2. The vertical portion of each lug is fixed to the crossmember, while their upper end 3a extends in a plane substantially horizontal and serves as support for the shield. These legs are distributed between the projectors blocks so as to offer regularly spaced support points to the shield. Preferably, these three legs are part of the same room. Figure 6 shows the shield 28, a portion of the inner face is supported on one of the support legs 3. These lugs 3 are preferably metal. The assembly formed by the searchlight blocks and support tabs thus provides support points for the shield which are preferably evenly distributed substantially all along the shield, the ends of the shield being fixed directly to the vehicle structure.
